Description

[Detailed explanation of the idea] The present invention relates to an improvement of a line hauler.

In longline fishing and vertical line fishing carried out on the coast, branch lines made of nylon threads or nylon monofilament (hereinafter simply referred to as nylon threads) are attached to main lines made of twisted yarn such as vinylon, or these branches are Currently, the main rope, which is the part where the rope is attached, is also made of nylon threads, and this is connected to the main rope made of twisted thread.

However, in conventional winding groove wheels for longline and vertical line fishing, a corrosion-resistant rubber band is attached to the groove wheel to prevent slipping and abrasion of twisted yarn such as vinylon, so when winding up nylon strings, the rubber band is attached to the groove wheel. The nylon threads bite into the band and the frictional heat causes them to wear out and break, and the rubber band is quickly damaged, so the nylon threads have to be rolled up by hand, which not only requires a lot of effort, but also requires a lot of effort. There are defects such as cuts.

The present invention is an attempt to improve these deficiencies, and consists of a small-diameter metal hoisting groove wheel that hoists nylon threads on the coaxial outer side of a metal hoisting groove wheel with a rubber band fitted into the groove. The gist is that they are integrated and connected.

An embodiment of the present invention will be described with reference to the drawings. A metal hoisting groove wheel 2 installed on the upper part of a hoisting machine body 1 and driven by hydraulic pressure or other means has a corrosion-resistant rubber band 3 fitted in its groove. In addition to preventing slips and abrasion of the main line made of twisted yarn, the winding groove wheel 2
Guide rollers 4 and 5 are provided at the front of the roller, and a pressure roller 6 is provided at the lower rear of the roller so as to press against the roller.
Furthermore, a small-diameter metal groove wheel 7 is coaxially and integrally provided on the outer side of the winding groove wheel 2.

Since the embodiment of the present invention is constructed as described above, the main rope A made of twisted yarn such as vinylon is guided onto the rubber band 3 of the winding groove wheel 2 via the guide rollers 4 and 5, and is pinched by the pressing roller 6. When hoisting the nylon thread B such as a branch line or a main line attached to a branch line, the metal groove wheel 7 is used to hoist it directly.

In this invention, the main rope made of twisted yarn such as vinylon fiber is hoisted by a hoisting wheel fitted with a rubber band, and the part made of nylon threads, such as the main rope at the branch line and branch rope attachment part, is hoisted by a metal groove wheel. Since it is hoisted with a nylon rope, long lines or vertical lines using nylon strings can be hoisted efficiently.
It has excellent features and practicality in that it allows for smooth and easy hoisting of ropes and also prevents damage to the rubber band of the hoisting groove wheel and cutting of the nylon threads.
